Split text by symbol (delimiter / separator)
Approachs
- Excel: (1) LEFT, RIGHT, FIND, LEN (2) MOD, FIND, LEN
- PHP: explode
- MySQL: MySQL SUBSTRING_INDEX() function - w3resource
Example
Task: Split 25.040215, 121.512532 by the comma ( , )
Expected output:
- 25.040215
- 121.512532
MySQL Approach
- to get the first string ( 25.040215 ):
SELECT TRIM(SUBSTRING_INDEX('25.040215, 121.512532' ,',', 1)) - to get the second string ( 121.512532 ):
SELECT TRIM(SUBSTRING_INDEX('25.040215, 121.512532' ,',', -1))
Excel Approach
| A | B | C | |
|---|---|---|---|
| 1 | 25.040215, 121.512532 | 25.040215 |
121.512532 |
If the data is perfect
- to get the first string ( 25.040215 ): B1 =
MID( A1, 1, FIND("-", A1)-1) - to get the second string ( 121.512532 ): C1 =
MID( A1, FIND(",", A1)+1, LEN(A1))
if the data was mixed with empty values. Return empty if the value is empty.
- to get the first string ( 25.040215 ): B1 =
IF(ISERROR(MID(A1, 1, FIND(",", A1)-1)), "", MID(A1, 1, FIND(",", A1)-1)) - to get the second string ( 121.512532 ): C1 =
IF(ISERROR(TRIM(MID(A1, FIND(",", A1)+1, LEN(A1)))), "", TRIM(MID(A1, FIND(",", A1)+1, LEN(A1)))
